I got a photo this morning after a short rain shower of the (apparent) mother turtle and her little ones. If you look closely, you can see the larger turtle with its head a bit out of the water, and right behind it, another smaller head belonging to her offspring. There are other young turtles swimming around, trying to gain her attention from time to time. I watched while this mother and her child swam around. Every time the mother stopped swimming and surfaced her head to the water, the baby would do the same right away. When the mother started swimming again, the baby did the same, right away.
I believe I saw a young turtle with a very tiny green turtle on its back, but I could not get close enough to see it clearly. Certainly looked like a baby green turtle.
Then today in this neck of the lake there was some kind of large fish -- two or more feet -- swimming right on the surface. There was a gang of them down there. I couldn't tell what they are, but hope to soon. Is there such a thing as still waters?
In the photo below the tree is a reflection in the water, but the green-leafed branches are from bushes by the lakeside. The turtles like to sun on shore along the bushes.
